I got Jade yesterday. He's a white halfmoon betta with red and blue accents on his fins. I've got pictures of him up in my albums, if you want to see him.

Granted, his side of the tank (I have a divider in a ten gallon-- Leliia's on the other side) has a little decor, but nothing to really hide in. He does wedge himself between the giant green rock and the divider, maybe that's his hiding spot.

Anyway, is it because he's in a new environment that he wants to attack any fish I've tried to introduce him to?
Even Dragon (a ghostfish) had to swim away like crazy. And he was in a bag. o__O
